Greubel Forsey GMT Balancier Convexe

The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.

Moonlight illuminates a botanical green dial. The “Fern Green” version of Perpetual Moon 41.5 borrows the cool tones of the moon. The paleness of the platinum, the freshness of the fern green, and the midnight blue of the sky create an original flow of colours.

Maturity, diversity and mechanical exclusivity: the Perpetual Moon collection is constantly being enriched with new creations, consistently reaffirming the watchmaking and artistic talents of Arnold & Son. Following two other editions, one with salmon pink accents and another in sky blue, Perpetual Moon 41.5 Platinum is now available in this limited fern green version of 28 timepieces.

Its hue is inspired by the unique colour of the fern, an undergrowth plant found in abundance in the English gardens of Cornwall, the county where John Arnold was born.

Inspired by the audacity and legacy of classical watchmaking, the Delphis Sapphire transcends conventional aesthetics with its striking sapphire blue hand-guilloché dial, setting a new standard in horological artistry. The Limited Edition of 50 is a testament to the harmonious blend of traditional craftsmanship and contemporary design crafted in the Atelier Lucerne. 
In the world of luxury watches, the Delphis Sapphire stands out. The brand's heritage is deeply rooted in extraordinary complications and daring designs, redefining the boundaries of watch design.

Armin Strom co-founders Serge Michel and Claude Greisler look back on 15 years of achievements including 17 exclusive movements, patents, unique designs and 97% in-house production depth. 15 years ago, Armin Strom transformed from a one-man show to a fully integrated manufacture brand when entrepreneur Serge Michel and master watchmaker Claude Greisler took over the reins.

Since 2009, the two childhood friends have been dedicating their lives to the science of movement, building up an independent manufacture with a team of 38, including 22 skilled watchmakers able to turn raw steel bars into hundreds of complex, interconnected watch components. So far, this has resulted in 17 brand-unique different calibres with a signature open-worked design divided among the brand’s three main pillars: System 78, Resonance and Masterpiece.

From the heart of Lucerne, the esteemed watchmakers at Chronoswiss are thrilled to announce the launch of three extraordinary timepieces that are set to revolutionize the luxury watchmaking landscape: The ReSec Helium Manufacture, ReSec Vertical Red Manufacture, and ReSec Obsidian Manufacture. These aren't just watches; they are marvels of engineering and design, crafted to push the very limits of horological artistry – all powered by the new Chronoswiss Manufacture Movement C.6005.
